Application filed March 3.

l1e it known that l. lxrlntfii ll'. nirns. a eiti/.en of' the l'nited States. residing at Pittshurgh. in the eonnty of A\lleg "hen}v and State of lennsvlrania. ha\e invented a new and useful linproveinent in Bottling-)laehines. of which iinprownient the following is a speeifieatitfn.

My in\ention relates to niaehines for filling hottles with liquids. and is partieularlj.' applieahle for use with aerated waters.

The ohieet of the intention is to prmide :1 siinple. rapid. etlieient and autoinatie n1a ehine of this eharaeter. in whieh the filling operation is dependent upon the presenee ot' a hottle on its support. while the amount of liquid eharged into the hottle ean he aeeuA ratel eontrolled.

My lnaehine provides ine-ans for filling hottles of about the saine euhieal eontents with the saine amount ot' water and provides an air reservoir whose euhieal eontents ean he varied. so that the air f'oreed out ot' the hottles ean he eoinpressed to a predeter- 1nine'l liinit within this ehainher. and thereh eheek the flow ot' filling litluid into said eha111her. By lneans of the adjustment of the eentents of this ehan1her. hottles ofa larger or sinaller eapaeit)Y ean he filled on the saine inaehine. 'l`he n1aehine also provides' for eontinuous operation. progressi\'el \Y filling a pluralit)v of' hottles.

fixed against lateral or sidewise movement and are arranged in longitudinal alinenient. so thatthe inoring parts thereof may he aetuated from a eonnnon shaft.

The tahle 23 has urnvardl)Y and downwardl)4 proieeting' hosses and il. whieli ser\e as guides for the reeiproeating rods 11i. arranged in pairs t'or eaeh ineelnuiisni. and extending therethrough. The upper and low er ends oll the-e rods are eoeueeted h1 the ero-s heads 1l andl 1".' respet'tivelv. and helow the eros-` har l1. :hote the tahle. the rods 1tl earr)v a third eross har 13. which slides freelY on said rods. This eross har 11E has stops 11. extending upwardl)V throi-igh holes in the eross har 1l. and arranged to liinit the upward tnorenient of the eross har 12X hv eontaeting with the top cross head t. Faeh eross har 121 inajf lle provided w ith two or more of these stops. whieh n1a he adviustahlv eonneeted thereto. as shown in the eentral hottle-filling deriee. ln the t'orni shown. the eentral hottle-filling de\ iee has two of these stops on its eross. hat' lil. while the other hars 13 eaeh ha\ e one stop 14. and also another stop eollar lil. extending out\\'-.1rdl}` t'ron1 the eros's har and engaging a stop eollar il.' on the side. support 5.

Yl`he nuineral 15 designates :1 earrier whieh is loosely mounted on the rods 10. and t0 whieh is eonnet'ted :1 tiller head lt'r. :l syrup punip 1V. and a \'al\'e '11'. for eontrolling the admission ot' aerated water into the ehanlher of the filling head.

1S designates eoiled springs whieh are seated around the rods 1U. hetween the earrier 15 and the eross hars lf. These springs seat within hollow sleeves 15* surrounding the rods 10 ahove the guide lugs of the earrier 15.

13 designates etlllars serured to the rods 1tl.helow the earriers 15. for the purpose ot' raising the earriers in the inanner hereinafter deserihed.

1.3" designates a guard or shield whit-l1 is eonneeted to a projeetion 15b on one of the eollars 15, This shield is designed to aet as a guard to .stop any fragments of glass. in ease of the hrealtage ot a hottle during filling. Only one ot' these shields is shown in the `drawings. hut it will he understood that a similar shield n1a he prorided for eaeh set ot hottling ineelranisnis.

The Valve 1T has a valve stein lil. extending upwardly therefrom in the line of movement of a lug 11 on the cross bar 11, said bar being arranged to move downwardly to .cause the lug 11a to engage said stem and open the valve during the filling operation in the manner hereinafter described. The syrup pump 16 is provided with an upwardly extending stem 20 which is connected to the cross bar 11 and is arvranged to be moved by said bar when the latter 1s moved relatively to the carrier 15.

The numeral- 22 designates an inlet leading from a source of aerated water supply to one side of the valve 17, and a connection leading from the other side of this A valve tn the filling head 16a.

24 designates the inlet from a syrup reservoir to the syrup pump 16. This syrup pump also has an outlet leading into the connection 23.

I will now describe the air chamber shown in Figs. 4 to v6. During the filling operation, the air expelled from the bottle being filled results in a pressure being built up within the chamber, but when this pressure becomes equal to the pressure of the aerated water supply, the flow of aerated water into the chamber will be stopped.

25 is^a cylinder which is secured to and extends upwardly from a boss or projection of the filling head 16a.

26 is a passage leading from the filling head 16 and communicating with the interior of the cylinder 25.

27 is a piston within this cylinder, said piston being connected to the lower end portion of a threaded rod 28, by means of a sleeve 29, and headed pin 30. This connection is of a character to permit the rod 28 to be freely rotated with relation to the piston. The rod extends upwardly through one of the tapped` openings in the boss 7 of the cross bar 6, and is provided at its upper end withA a hand wheel 31, by means of which it may be turned to raise and lower the piston 27.

32 is a second cylinder which surrounds the cylinder 25 and which has a head 33.

34 is a tubular piston rod surrounding the cylinder 25 and extending through the cylinder head 33; and 35 is a piston at the lower end portion of the tubular piston 34, the piston 35 having suitable packing forming an air-tight joint between it and the wall of the cylinder 32. The upper end of the tubular piston 34 is provided with a suitable packing to prevent leakage between it and the cylinder 25, and the joint between the cylinder 32 and the filler head is also suitably packed. The cylinder 25 has ports 36 at its lower end which form a means of communication between the two cylinders 25 and 32, when the piston 35 is elevated above these ports. The piston rod 34 has projections 37, which are arranged to register with recesses 38 in the cylinder head 33 when the piston 35 is moved down to the position in which it is shown in Figs. 4 and 5. After the piston 35 has been thus moved down, it is rotated from the position shown in Fig. 4 to that shown in Fig. 5, in order to lock it and its rod in their lowermost positions. Any number of these projections 37 may be provided, so that the piston 35 can be locked at any desired point intermediate of the two positions shown, respectively, in Figs. 4 and 6.

If the machine small bottles, the piston position shown in Fig. manner just described. then raised or lowered relative to the size of the air chamber, so that the pressure built up within this chamber will equalize that in the aerated water supply pipe and stop the flow when the predetermined quantity of liquid has been charged into the bottle. To fill larger sized bottles, the piston 35 is raised, and if necessary, the piston 27 can then be moved to obtain a more accurate adjustment of the air chamber.

In Figs. 1 and 2, I have shown the air chamber formed by a single cylinder 25, which is similar to the cylinder 25, except that its lower end is not provided with the ports 36. One or more cylinders may be used for the equalizing chamber, the number and size of the cylinders being governed by the requirements of the particular machine.

The numeral 40 designates a power shaft journaled in the base standards 2 2, and having a driving pulley 41, or any other suitable driving connection.

42 is a rod which connects the standards 2, 2, and extends across the front of the machine. '1" he shaft. 4() carries the operating cams 43 and 44 for each bottle-filling mechanism. The cam 43 contacts with a roller 48, pivotally mounted in the lever 47, loosely pivoted to the rod 42; while the cam 44 contacts with and actuates roller 45, which is iournaled on the depending projection 46 of the cross head 12. Springs 49 connect the levers 47 with the cross bar 12 and act to move the cross bar and the @ments connected thereto downwardly when the lever is actuated by the cam. These springs also compensate for varying heights of bottles and give an automatic adjustment therefor. The springs are connected at their ends to stems or hook bolts secured by nuts. The cams for the different filling mechanisms are set out of time with each other and are arranged to move the filling mechanisms with relation to the bottle supports in the continuous rotation. of t'ze power shaft. lt will therefore be see` th t each set of bottling mechanisms comprises means for support- /i.ng the bottle, this being the table 3; means relatively 35 is moved to the 4, and locked in the is to be used for The piston 27 is,

Ase

for bringing the filling meehanisni and the supportingl means into filling relation: a source ot still liquid supply: a souree ot' charged liquid supply; and means controlled by the presenee ot' a bottle on the bottle support for eontrolling the diseharge of liquid from these two soui'ees. a quantity of still liquid being first discharged. at'ter which the valve controlling.r the supply ot charged liquid is opened to admit a supply ot' the latter to the tilling head` The operation of the maehiiie is as t'ol'- lows: Assuming the parts to be iii their elevated positions. in whieh the roller 1T is engaged by the point V11" ot' the eam l1. and the roller lo is bearing against the tlat poi'- tion 43" of the eam 123. the bottle to be lilled is plaeed on the table I1 below the tilling head 10a. As the shaft lll is rotated. the eain -11 will move from under the -roller 15 and permitithe eross bars and the rods lll. together with the various elements mounted thereon. to move downward by gravity until the neel: ot the bottle is engaged by the mouth of the filling head. whieh will arrest the movement ot' the earrier 15. The t'ur thei' rotation ot' the shaft i0 will aetuate ithe lever 1T through the medium ot the eain 453 and move the rods 1o downward to their lowermost position. which position will be reaehed when the roller lo is engaged by the coneentrie portion 491" of the cani 1?). During this downward movement of the rods 1U. the neck ot' the bottle engagingthe mouth ot' the filler head will be pressed thereon with sutlieient pressure to forni an air-tiglit lioint. 'hen the carrier 13 is :stopped from t'urther downward movement. the further iuoveiiient of the rods 10 will move the eross bars 11 and 115. thereby eompressing the springs 1S (whieh are seated iii eounterbored portions ot' the loose sleevesl 15 on the earrier 15) sutlieiently to thereby .stop the rods 1u and eross bars 11 and 121 from t'urther movement. The further movement of the lever 1T through the medium ot' the rain Y1?). after the rods 10 have been stopped from t'urther movement by the engagement of the eross bar 133 and the guide lugs; on the earrier. will be taken up by extending the springs sld. During the downward movement of the eross-bars 11 and 121. i'elative to the carrier 17. the syrup pump will tirst be actuated by its eonneetion with the bar 11 to inielet the syrup into the bottle being filled. and the lug 11 will then strike the valve stem 1.) and open the valve 1T. to permit the aerated water to How into the bottle. whieh will take plaee while the eoneentrie portion li of the ram 4? is passing' over the roller J. A\.s soon as this portion of the eani passes otll the roller ln. andthe tension ot' the springs 1i* has been relieved. the springs 1`. through the erossbars 11 and lil. will raise the rods 111. which will. in tui-n.

through the engagement of the eollars 13 with the earriers 13. raise .said Carriers and the filling head to the position in whieli the parts are shown in the middle tiliing ine-hanism ot' Fig. 1. The roller i3 will then be engaged by the eam ll and raise the rods. together with all ot' the elements mounted thereon. through the medium ot the eollars 13a. until the movement ot the eross` bar 121 is arrested by the stops 1i. The further upward movement ot the earrier 1f will eonipress the springs 1S. and move the earrier and filling nozzle relative to the eioss har 123. to permit the removal otl the bottle from the filling head. It' either of the lillingr deviees should he moved downward. when there is no bottle below' the lilling head. all of the element.s eonneeted to the rods 1U would move together without actuating the syrup pump or openingr the valve 1T. lt will therefore be noted that the hars 11 form normally inoperative aetuators for eontrolling the admission of liquid. these being rendered operative by the prevention of the downward movement ot the bottle-filling head when the bottle is present. lii other words. when the bottle is present in one of the meehanisnis` it prevents downward movement ot' the bottle-filling head. and thereby holds the valve stem 111 in a position where it will be aetuated by the lug 1l. In sueh ease. the bottle also eauses the neenessary relative movement to take place between tlie syrup pump attaehed to the filler head and the bar 11 to etleet the opei'atioii ot' the pump.

lv reference to Figs. 1. T. T and T". it will be seen that the three maeliines will be operated successively. Figs. T. T and Tb show the Canis 13 and 1l t'or aetuating the three iiiaehines' and also show the eams in their relative positions with relation to eaeh other. Ilaeh set otl eams is set 121V from the set o1' eams adjaeent thereto.

The advantages of my invention result from the provision of an autoiiiatie machine of a simple and improved type for filling bottles. By means` of this maehine. bottles may be filled at a high speed and with aeeuraey and precision. The filling operation is dependent upon the presenee ot' a bottle on its support. The maehine is eapable ot' filling bottles of various ,sizes and eapaeities. By means of the closed pressureehanibers in the filling heads. the amount of liquid going into the bottles ean be eontrolled.

In eonneetion with the maehine. l will. ot` eoui'se. use` any suitable form of elosure-applying meehanism. sueh. for example. as that of ill Patent No. 1113.915. dated February 2U. loot).
